How to use Enums in UITableView properly?

Question

In my ViewController I've created an Enum:

enum ItemType: String {
    case Restaurant, Boutique, Resort
}

in didSelect I use:

self.performSegueWithIdentifier("goToItemsList", sender: ItemType.Restaurant.hashValue)

later, in:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "goToItemsList" {
        let itemsListTableViewController = segue.destinationViewController as! ItemsListTableViewController
        itemsListTableViewController.cellType = sender!
    }
}

So, how can I now check in my ItemsListTableViewController

if cellType == .Restaurant {
   // Do something
}

? I know, for this, I need do something like:

var a: ItemType

and just later to check that, but I cannot set the type of my a to ItemType in my ItemsListTableViewController.

Can anyone help me with that?

Answer 1

you can simply do like this

in didSelectRow

you can use rawValue property. it returns The corresponding value of the "raw" type.

self.performSegueWithIdentifier("goToItemsList", sender: ItemType.Restaurant.rawValue) 

and in prepareForSegue

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "goToItemsList" {

  let itemsListTableViewController = segue.destinationViewController as! ItemsListTableViewController
  itemsListTableViewController.cellType = ItemType(rawValue: sender! as? String)
}
}

and in other view controller

var cellType :ItemType?

either you can directly check or can use switch

if let value = cellType {

switch(value) {

case .Boutique: // do something here
 break
case .Resort: // do something here
break
case .Restaurant: // do something here
break
}

}

Answer 2

You can access the enums from your ViewController like:

ViewController.ItemType

Or, to match your example:

var a : ViewController.ItemType
